IMPROVEMENT IN CRIMPING WIRE-CLOTH.

lSpcclication forming part of Letters Patent No. 49.356.. dated A11-gust 8, 1865.

To all whom 'it may'concern:

Be it known that LWILLIAM ZERNs, of Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Improvement in Crimping VVire-Cloth; and I do hereby declare that the following is a full, cica-r, and exact description thereof', which will enable thosefskilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section of the device or means employed for carrying ont my invention; Figs. 2 and 3, face views of the same; Fig. 4, a section of a pieeeof wire-cloth before being crimped by my improved mode; Fig. 5, a plan or face view of a piece otf wire-cloth crimped according 'to my invention.

, Similar letters of reference indicate correspondin g parts.

Wireeloth of the coarse kind require to have the wires crimped or bent in order tobringv the same as near as possible to a plane surface and retain the Wires in position. Hitheto the wires have been crimped before the weaving process; but by my improvement I crimp them after they are woven by means of toothed plates, as hereinafter set forth.

A A represent two metal blocks, which are of rectangular form,.and have steel teeth a inserted in them, ot' oblong form, as shown in Figs. 2 and 3. These teeth a4 have such a position that when a piece of'Wre-cloth, B, is insert'ed between the blocks` A A the teeth a will crossthe wires at right angles,ns indicated in red in Fig. 5, and when the blocks have pressnre applied to them the wires will be bent or crim pcd at both sides, or double-crmped, as

then crimped by meansof,thetoothedplates as described.

I claim as new and desire to secure by Letters Patent The crimping of wire-cloth by placing the same, after being woven,- between toothed plates and subjecting it to pressure, substantiallyas set forth.
